The precision assembly of this sub-platter integrates ideal components into a single sub-platter design which is not available anywhere else: polished aircraft grade aluminium hub (6061-T6 grade aluminium) with low carbon stainless steel extended spindle (316L stainless steel) and a dual butyl rubber inserting at hub and spindle as wide and efficient isolator, decoupling stages and, of course, to have a perfect platter gripping.
Maximum height oscillation at the edge of an original Rega platter = 0.05 mm or 0.002 inches
